Sorting Seeds

We started out first unit in science last week: plants. However, it's been a little slow getting it started since we keep having early outs on Mondays...that's one of our few science days :( The first day we discussed the 3 main differences between plants and animals. Then we also labeled the 3 main plant parts. Yesterday we learned all about seeds. We cut into 8 foods and examined their seeds: cucumber, tomato, squash, lemon, orange, grapefruit, melon, and green pepper. The students pretended they were detectives and they investigated the various seeds. They learned that tomatoes have VERY small seeds. Melons have a LOT of seeds. Oranges, lemons, and grapefruits don't many seeds. In fact, I had several students dig FOREVER and never find an orange or grapefruit seed. How is that possible????? We saved all the seeds for a later project. More to come on seeds and other plant parts...
